Anyways, work progressed on this project last night, made a drive drawer, cut out more metal for the fan, and got the turbine mounted PROPERLY. All I have left to do is to bondo up the turbine, install the window in the side, and paint the front panel.

What should I use to layer a 1" thick coating around the blowhole, to giive it shape. I was going to use bondo, but I heard that cracks when it is in thick coats, then I thought about expanding foam, but I heard that was very hard to work with.

So, I need some kind of modeling putty, or equivalent, that I can get at a hardware store.
